Error Management Operator Detection

Question

Please tell me if this is correct. In my error handler, I should be able to detect when the @ error-control statement was used to suppress errors, because some external libraries (unfortunately) use it a lot. Script execution should continue as if you were not using custom error handlers.

When the at sign is used, PHP temporarily sets error_reporting to 0. Thus, at the beginning of the script, we set error_reporting to any value, but zero - now we can do some beautiful IF / ELSE magic. To avoid errors displayed in the external interface, we also set display_errors to 0, this will override error_reporting (but we can still use this value for magic).

<?php

ini_set('display_errors',0);
error_reporting(E_ALL);

function error_handler($errno, $errstr, $errfile, $errline)
{
    if (error_reporting()===0) return;
    else die();
}

set_error_handler('error_handler');

//This issues an error, but the handler will return and execution continues.
//Remove the at-sign and the script will die()
@file();

echo 'Execution continued, hooray.';
?>
